Exodus 19:14-16

Darby Translation

¹⁴ And Moses came down from the mountain to the people, and hallowed the people; and they washed their clothes.

¹⁵ And he said to the people, Be ready for the third day; do not come near [your] wives.

¹⁶ And it came to pass on the third day, when it was morning, that there were thunders and lightnings and a heavy cloud on the mountain, and the sound of the trumpet exceeding loud; and the whole people that was in the camp trembled.
